Mr. Smith creates a new sauce because he wants to increase his restaurant’s sales by creating a burger that reduces gas producti

on. He recruits 100 customers with a history of gas problems. He has 50 of them eat burgers with the new sauce. The other 50 eat burgers with sauce that looks just like the new sauce, but it is really just a mixture of mayonnaise and food coloring. Both groups were told that they were getting the new sauce. Mr. Smith has all of the participants track their production of gas for 24 hours. Mr. Smith finds that customers who ate the new sauce had less gas production for 24 hours.

A sample weighing 3.110 g is a mixture of Fe 2 O 3 (molar mass = 159.69 g/mol) and Al 2 O 3 (molar mass = 101.96 g/mol). When he
grandymaker [24]

Answer:

The mass fraction of ferric oxide in the original sample :\frac{723}{3110}

Explanation:

Mass of the mixture = 3.110 g

Mass of Fe_2O_3=x

Mass of Al_2O_3=y

After heating the mixture it allowed to react with hydrogen gas in which all the ferric oxide reacted to form metallic iron and water vapors where as aluminum oxide did not react.

Fe_2O_3(s)+3H_2(g)\rightarrow 2Fe(s)+3H_2O(g)

Mass of mixture left after all the ferric oxide has reacted = 2.387 g

Mass of mixture left after all the ferric oxide has reacted = y

x=3.110 g- y=3.110 g - 2.387 g = 0.723 g

The mass fraction of ferric oxide in the original sample :

\frac{0.723 g}{3.110 g}=\frac{723}{3110}

What is the physical property to all of these (pls answer I’ll give brainliest)
Sav [38]

Answer:

Explanation:

Brittleness : The ability of an object to break apart or shatter easily

Ductility: The ability of a substance to be stretched out into a long wire-like shape.

Lustre: the ability of an object to reflect light.

Malleability is a substance's ability to deform under pressure

The melting point of ice is 0°C. The melting point of a solid is the same as the freezing point of the liquid

Solubility is the relative ability of a solute to dissolve into a solvent.

solid: Has a definite shape and volume.

liquid: Has a definite volume, but take the shape of the container.

gas: Has no definite shape or volume. change of state

The resistance of a liquid to flowing is its viscosity.
